Physical and chemical indicators:
Name of indicator: | Indicator | |
National standard | Company standard | |
Al2O3∕%≥ | 29.0 | 29-30 |
Basicity∕% | 40-90 | 60-85 |
Density (20ºC)∕（g/cm3）≥ | 1.12 | -- |
The mass fraction of insoluble∕%≤ | 0.6 | 0.3 |
PH value (10g/L aqueous solution) | 3.5~5.0 | 3.5-5.0 |
As ∕%≤ | 0.0002 | 0.0002 |
Pb∕%≤ | 0.001 | 0.001 |
Cd∕%≤ | 0.0002 | 0.0002 |
Hg∕%≤ | 0.00001 | 0.00001 |
Cr6∕%≤ | 0.0005 | 0.0005 |
Note: indicators of As, Pb, Cd, Hg and Cr6+ insoluble of liquid products listed in the above table should be calculated by Al2O310%. When Al2O3 content is ≥10%, indicators of impurities should be calculated by converting the actual content to Al2O310% product proportion. | ||
Every 25Kg of solid products should be put in one bag with inner plastic film and outer plastic woven bag. Products should be stored in the dry, ventilated and cool place inside the door for fear of damp. Don't store them together with inflammable, corrosive and toxic goods.
